[Bug 1829829] Re: Ubuntu CI has been flaky for a week

> it looks like @laney is listed there, which is probably appropriate
(he has admin access to the test systems, while I don't)

My understanding is that @laney can help with the infrastructure where
the tests are run. What usually happens on Ubuntu CI for the most part
has nothing to do with the infrastructure. I'd say it's pretty stable
except that for about a month if I recall correctly it failed to report
the statuses of PRs but it was fixed by @laney in
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1817344.

Regarding TEST-34 on i386, could you open an issue on GitHub? It could
probably be kept on the list as well until it's fixed.

  Though judging by https://github.com/systemd/systemd/pull/12626, it
  appears that sometimes the tests pass.
